  Log Message:
  -----------
  [Instrumentor] Add runtime examples: [1/N] A flop counter

This adds a instrumentor-tools folder into compiler RT to showcase
use cases of the instrumentor. The initial example is a program that,
via instrumentation, counts the number of flops performed. Call and
intrinsic support will follow after #198042.

Partially developped by Claude (AI), tested and verified by me.
